Abstract: A method of treating protozoan infections in fish comprising introducing a sufficient quantity of one or more photoactive dyes to an aqueous environment containing one or more fish infected with protozoa such that the resulting concentration of the one or more photoactive dyes in the aqueous environment is toxic to at least some of the protozoa.
